Digitization of civil architecture objects during wartime using photogrammetry: A case study of Sumy State University

INTRODUCTION: In the context of the ongoing war in Ukraine, the preservation of architectural heritage has become critically important. In this regard, the documentation and preservation of architectural heritage have become crucial. OBJECTIVES: The study employs drone-based aerial imaging and terrestrial photography to generate accurate 3D models of a partially destroyed historic building. METHODS: A photogrammetric technique was employed to create an accurate 3D model of Campus K-2 of Sumy State University, destroyed by russian missiles on April 13, 2025, in Sumy, Ukraine. A comprehensive approach for involving photogrammetric reconstruction, texture processing, and building information modeling (BIM) integration was described. The research also outlines the challenges of restoring during wartime, discusses data acquisition and processing workflow, and evaluates the effectiveness of low-cost equipment and open-source software in achieving high-quality results. RESULTS: The resulting digital model captures structural deformations and facade details. The implemented approach enables documentation and monitoring of damaged structures. It also provides valuable fundamentals for the studied object’s future restoration, structural analysis, and memorialization. CONCLUSION: The research shows photogrammetry as a fast, reliable tool for documenting cultural heritage in wartime and emphasizes its social value for education and preservation. It also suggests adding protective architectural features to reconstructed heritage buildings to improve resilience in conflict zones.
